Al-Iman Masjid — Site Survey Field Form نموذج المسح الميداني

One field walk to capture everything the design is still waiting on. Every item below is a real gap in our model (a PLACEHOLDER or TBC). Fill it on-site, hit Export answers, send the file to Cici — each answer flips a placeholder to MEASURED and unlocks the vendor/procurement stage. Autosaves in this browser as you type.

🟥 blocks a deliverable 🟧 improves accuracy 🟩 nice-to-have Tip: tap a zone to open it. Boxes save automatically.
00 Confirm with the board / imam

Decisions only the masjid can make قرارات الإدارة

Not measurements — ask أبو سليم / the imam / the committee. These unblock the whole design direction.

🟥Main hall (Z1) sound target: khutbah clarity (RT 1.2–1.6 s) or recitation warmth (~1.8 s)?
Sets the whole tuning philosophy + whether any LF treatment is offered.
🟥Outdoor athan SPL limit from the minaret (board / neighbours)?
Sizes the minaret loudspeakers + amplifier.
🟧Existing PA per zone: keep / augment / replace? (women's = replace already confirmed)
Decides reuse vs full supply per zone.
🟩Wireless mics — CONFIRMED wanted · RF is fine in Syria (D-12, no longer a blocker). Channel count set by Obai 2026-08-19.
Feeds the BOQ wireless line.
🟥Budget tier / band — best-for-room vs Syria-serviceable fallback?
Drives the whole BOQ + which loudspeaker class.
🟩Rough peak # of simultaneous dars + which rooms are dars-capable?
Only tunes spare-capacity margin — not a blocker.
🟥Board ratifies room IDs — is Z5 the library (مكتبة, mezz SE)? Is Z7 the ablution (ميضأة, west basement)? Staff identified these; the board must confirm the official use + name.
Locks which zones get PA + the BOQ line items. Pending until the committee signs off.
🟩One photo straight up the dome (apex, from directly below) — ask the board/caretaker to send it.
Firms the dome interior finish for the ray-trace; not a blocker.
01 Zone-by-zone walk

Every space — measure & confirm جولة على كل منطقة

For each zone: tick what you confirm, fill the measurements (units shown), note the finishes, and grab the photos. Clear height is the single most-wanted number almost everywhere.

Z1Main Prayer Hall — domed القاعة الرئيسية▾
Our model: 1002 m² measured from CAD, box 36.96×26.47, mean height ~9.7 m. The dome is its own section below. Floor carpet, plaster walls, marble mihrab — mostly known. Missing: window heights, colonnade closure, finish confirmation.
🟧Window heights (CAD gives widths ~1.65 m only) + count per wall
m high
# count
🟧South colonnade closure: are the wood partitions + curtains present? Coverage?
🟧Finish check by touch: mihrab real marble vs painted? carpet underlay? curtain coverage %
🟩Existing PA in the hall (models, mounting, condition)
Photos: each wall, mihrab close-up, a window with a tape for scale, ceiling coffers.
DOMEThe dome — vertical profile القبة▾
Why it matters most: the dome drives the whole acoustic story (crown echo + focusing). CAD gives only the plan circle (Ø ≈ 8.54 m). We have zero vertical data — everything above is currently schematic.
🎯 No ladder needed — laser from the floor. Use a laser distance meter (an inclinometer type like Leica DISTO / Bosch GLM is ideal). Apex height = stand under the crown, shoot straight up. Spring line = shoot to where the curve meets the drum wall. Rise = apex − spring. With the plan radius already known (Ø 8.54 m), that defines the profile. Angle-capable laser? Take a few distance+angle shots up the curve for the exact shape.
🟥Apex height above the floor (laser straight up at the crown)
m apex
🟥What does the CAD height H = 20.80 m refer to — apex, drum spring, or soffit?
🟧Spring-line height (curve meets drum) + drum height + rise (apex − spring)
m spring
m drum
m rise
🟧Interior dome material / finish (plaster, decorative, painted, gilded?)
Photo — one shot straight up at the dome centre (the one image we couldn't get). + any drum windows.
Z1bSouthern Columned Expansion التوسعة الجنوبية▾
Our model: 727 m² (CAD footprint), bay heights ~4–5 m. Missing: is it prayer-overflow or madrasa? bare-blockwork west wall finish, openings, closure.
🟧Function: prayer overflow or madrasa/multi-use?
🟧Clear height(s) of the bays (3 sub-bays)
m
🟧Will the bare blockwork west wall be finished? With what?
🟧Window heights + count; partition/curtain coverage on the colonnade line
Photos: west blockwork wall, the colonnade line, ceiling.
Z2Mezzanine + expansion السدّة▾
Our model: ALL placeholder. CAD height annotations span a wild 3.45–8.87 m. Open to the hall below (acoustic coupling). Dual-use: occasional women's + the library is carved into its SE corner.
🟥Clear height(s) of the mezzanine + which of the 3 sections is which
🟧Mezzanine floor level above ground + footprint of the 3 sections
🟧How open is it to the hall below? (balustrade glazed or open rail?)
Photos: the gallery, the balustrade edge, floor finish.
Z4Women's Section — basement south قسم النساء▾
Our model: official women's hall = south basement, 649 m² (CAD-measured, client-confirmed). Missing: the basement clear height (no CAD annotation anywhere) + any internal partitions.
🟥Clear height of the basement (drives RT for Z3/Z3c/Z4/Z7 too)
m
🟧Internal partitions inside the women's hall? Floor/wall/ceiling finish
🟥Existing conduit: audio + power currently share a conduit (interference). Confirm route for a NEW dedicated audio conduit
Photos: the hall, the shared conduit/cabling, existing speakers.
Z3Basement daily-prayer rooms قاعة القبو▾
Our model: north basement, ~8 partitioned rooms + corridor, all placeholder. Which are prayer vs dars? Per-room dims + the shared basement height.
🟥Basement clear height (same slab — confirm once)
m
🟧How many rooms? Which are prayer vs dars? Rough dims each
🟩Finishes (carpet, wall, ceiling type) + any existing speakers
Photos: each room, corridor, ceiling slab.
Z3cBasement corridor ممر القبو▾
Our model: placeholder. Very live (bare surfaces) → paging-grade only. Need extent + section.
🟩Corridor length × width + height; surfaces (bare concrete/tile?)
Z5Library / Lesson hall المكتبة▾
Our model: mezzanine SE angled room, ~119 m² (identified from photos, board-pending). Open question flagged by the audit: is the adjacent 98 m² room part of the library? Height is placeholder.
🟧Is the adjacent ~98 m² room part of the library? (this decides the box count)
🟧Clear height + used for lessons needing reinforcement?
m
Photos: the room + the adjacent room + the doorway between them.
Z7Ablution / wet area الميضأة▾
Our model: located west of the basement via "باب الميضأة" but its room boundary isn't in the CAD — a western annex. Wet + humid → needs IP-rated gear.
🟧Where exactly is it? Room dimensions (L×W×H) — it's off the drawn plan
🟧Conditions: standing humidity? splash zones? ventilation? (drives IP rating)
Photos: the الميضأة door, the room, wet surfaces, any existing speaker.
Z6Minaret / outdoor athan المئذنة▾
Our model: outdoor, IP66, 70 V. All mounting/throw data missing. This is a 🟥 blocker for the outdoor part.

02 Acoustic measurements

On-site readings قياسات صوتية

Use the RT60 playbook (03-site-survey/RT60-MEASUREMENT-PLAYBOOK-AIM.html). Balloon-pop or sine-sweep per hall; note occupied/empty.

🟧RT60 per hall (main, south, mezzanine, basement, women's) — attach the recordings
🟧NC / background noise per hall — AC towers + fans ON and OFF
🟩Confirm the survey-day temp + RH is logged at the top (air absorption)
03 PA · electrical · existing system

What's already there & what we can use النظام الحالي والكهرباء

🟧Existing PA inventory: every speaker/amp/mic — models, where, condition (4TONE + others)
🟧Amp / rack room location + space + ventilation + existing racks
🟥Cabling / conduit condition + routes; women's shared audio+power conduit confirmed?
🟧Power: available circuits per zone; is a dedicated clean supply possible? generator/backup present?
🟧Network path (Dante): can cable run between zones + to the rack? riser locations
🟧Mounting points: solid walls/columns for arrays at the qibla; ceiling access for the basement/library
04 Access & logistics

So install day has no surprises الوصول واللوجستيات

🟧Working hours / prayer-time constraints; who authorises access (أبو سليم)?
🟩Heights = laser from the floor (no ladder). Ladder/access only needed to physically inspect the minaret platform (power, mounting, cable route) — available, or bring?
🟧Tools to bring: laser distance meter (inclinometer type), tape, SPL meter, sweep/balloon for RT, camera
🟩DARS series start (Sept 1) — which rooms must be live first?
🟩Any site plan / newer CAD sheets the architect can hand over on the day?
When you're done: hit ⤓ Export answers (top right) — it downloads a filled summary. Send that file to Cici and every answer flips a PLACEHOLDER → MEASURED, the engine re-runs, the loudspeaker schedule firms up, and we're clear to go to the vendor for a real quote.
